+
+A duplicate job in the sense we use it here means a second or subsequent job
+with the same name starts. This happens most frequently when the first job
+runs longer than expected because no tapes are available.
+
+ If this directive is enabled duplicate jobs will be run. If
+ the directive is set to {\bf no} (default) then only one job of a given name
+ may run at one time, and the action that Bacula takes to ensure only
+ one job runs is determined by the other directives (see below).
+
+ If {\bf Allow Duplicate Jobs} is set to {\bf no} and two jobs
+ are present and none of the three directives given below permit
+ cancelling a job, then the current job (the second one started)
+ will be cancelled.
+
+\item [Allow Higher Duplicates = \lt{}yes\vb{}no\gt{}]
+\index[general]{Allow Higher Duplicates}
+ This directive was implemented in version 5.0.0, but does not work
+ as expected. If used, it should always be set to no. In later versions
+ of Bacula the directive is disabled (disregarded).
+
+
+\item [Cancel Lower Level Duplicates = \lt{}yes\vb{}no\gt{}]
+\index[general]{Cancel Lower Level Duplicates}
+ If \textbf{Allow Duplicates Jobs} is set to \textbf{no} and this
+ directive is set to \textbf{yes}, Bacula will choose between duplicated
+ jobs the one with the highest level. For example, it will cancel a
+ previous Incremental to run a Full backup. It works only for Backup
+ jobs. The default is \texttt{no}. If the levels of the duplicated
+ jobs are the same, nothing is done and the other
+ Cancel XXX Duplicate directives will be examined.
+
+\item [Cancel Queued Duplicates = \lt{}yes\vb{}no\gt{}]
+\index[general]{Cancel Queued Duplicates}
+ If {\bf Allow Duplicate Jobs} is set to {\bf no} and
+ if this directive is set to {\bf yes} any job that is
+ already queued to run but not yet running will be canceled.
+ The default is {\bf no}.
+
+\item[Cancel Running Duplicates = \lt{}yes\vb{}no\gt{}]
+\index[general]{Cancel Running Duplicates}
+ If {\bf Allow Duplicate Jobs} is set to {\bf no} and
+ if this directive is set to {\bf yes} any job that is already running
+ will be canceled. The default is {\bf no}.
+

+%% This directive permits to determine if two jobs are really duplicated.
+%% If the first one is running for long time, this is probably not a good
+%% idea to cancel it.
